This is true. Marvel Studios COULD have made a Namor or Hulk movie at any time .... had they wanted to share the profits with Universal. Obviously, that wasn't going to happen. But rumor says Universal may be losing those rights, so we could see movies for them. I do think a Defenders movie is more unlikely, in part because of the foolishness of using the name for the Netflix team. I could see them using the team in a Dr Strange movie, without giving them an official name.
